Thanks, John. I'm fairly familiar, at this point, with the various screen 
change notifications available. It's just that if I want to take action when 
the screen changes, I don't want to be fighting with the OS to position my 
windows.

NSApplication class has a notification you can observe:

NSApplicationDidChangeScreenParametersNotification

Posted when the configuration of the displays attached to the computer is 
changed.
The configuration change can be made either programmatically or when the user 
changes settings in the Displays control panel. The notification object is 
sharedApplication. This notification does not contain a userInfo dictionary.



Then you can respond according to your app's needs.
Presumably, you should not rely on or infer the logic of what the system does 
for you, but rather just respond as appropriate for your own needs.

Thanks, Ken. It seems like it keeps windows pegged to the nearest corner. I 
haven't tried it with windows larger than a screen quadrant, only a tiny window.

I believe the top-left corner is kept in the same relative position to the 
top-left corner of the screen, unless that would leave part of the window 
off-screen.  If it would, then the top-left corner is moved to get the window 
fully on-screen, unless the window is too large to fit entirely on screen.  In 
that case, the top-left corner is moved to a few pixels in from the top-left 
corner of the screen (excluding the menu bar).  I don't recall if the window is 
resized to fit on the screen or just left with its bottom and/or right side off 
the screen.

I could swear I've seen a rough description of this somewhere, but I'm not 
finding it now.

Regards,
Ken

So try it with a random sampling of 20 window sizes and positions, and log the 
window and screen frames before and after the screen change. If you post the 
results here on this list, someone may spot a pattern.

Yes. But I'm reluctant to talk about it just yet. In any case, it would be 
helpful to me to know.

I can't imagine why it would be documented anywhere. Is there some reason you 
need to know what it's doing?

Window positioning and screen resizing

2013-05-13 Thread Rick Mann
It seems that Cocoa or the OS or someone repositions my windows with some rules 
when the screen resolution changes. Does anyone know what the rules are? Stuff 
is kept in roughly the same quadrant of the screen, near as I can tell, and 
perhaps the offset within the quadrant is adjusted by some factor, but it seems 
to be repeatable (that is, windows don't crawl with repeated changes).

Is this documented somewhere? I couldn't even think of how to search for this 
(my feeble attempts turned up nothing).
